You don't want grease anywhere near your lenses.

Seconded. There are `non-creep` greases, but even so... Plus, as you
have discovered, I think you will find it very hard to get apart.
Frankly, I can't see why it would revolve unless your camera is
vibrating, which can't be good for image quality...

I would just cut off a piece of a good quality removable-adhesive
label, and stick that on the side.

If it's brand new I'd return it for a new one. If it's not working now you
might as well get a new one that works and save you all of the bother.

Thanks anyway. I figured it out under a magnifying hood. The front ring
that revolves is bent over (beveled) slightly over the rear piece (rolled
edge or swaged fit??).

I soaked the thing in silicon oil, found a large socket that just about
doesn't go through the rings with the glass filter out, sat it on a hardwood
block, and smacked it with a hammer from the backside. The thing now
revolves as it should. It was way too loose from the factory and maybe had
a 0.050" amount of looseness in the front (I could easily stick my
fingernails in between them. The glass filter itself was loose as well and
wasn't aligned with the "Sun Dot." It was a rattle trap in two places and
the revolving polarizer filter glass was making another issue in itself
(thanks to black silicon it won't do that again!).

All washed it up with Simple Green and it is better than new, and I don't
have to Mickey Mouse the thing anymore -- I hope.

I know you said you washed it all up, but be *very* careful with
silicon compounds as they are notorious for going places you don't want
them to, and if it gets on/under coatings or between elements of a
lens...

My buddies over at Penn Camera (right across from the FBI building in
DC) steered me away from a $45 polarizer due to fit 'n finish. The price
difference wasn't too much in a 67mm but it feels tighter.
